Secondary Spinal Cord Injury llI: Pathophysiology01:25

Secondary Spinal Cord Injury llI: Pathophysiology

Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...

Parkinson's Disease: Overview

Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is to...
Multiple Sclerosis l: Introduction01:19

Multiple Sclerosis l: Introduction

Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...
Parkinson Disease ll: Pathophysiology01:24

Parkinson Disease ll: Pathophysiology

Parkinson disease (PD) is a progressive neurodegenerative disorder primarily affecting movement, with additional non-motor features. Its pathophysiology involves complex interactions among genetic susceptibility, environmental exposures, and cellular dysfunction, including dopaminergic neuron loss, protein aggregation, and mitochondrial impairment.Selective NeurodegenerationA key feature is the degeneration of dopaminergic neurons in the substantia nigra pars compacta, leading to reduced...
Spinal Cord Injury ll: Pathophysiology01:14

Spinal Cord Injury ll: Pathophysiology

Spinal cord injury progresses through two interconnected phases: primary injury and secondary injury.Primary InjuryPrimary injury happens at the moment of trauma and involves immediate mechanical damage to the spinal cord.Compression happens when broken vertebrae, herniated discs, or accumulating blood (such as a hematoma) press directly against the spinal cord, distorting its normal shape and function. In cases of contusion, the cord is bruised by a blunt force (like penetrating injuries or...
Alterations in Muscle Tone lll01:11

Alterations in Muscle Tone lll

Rigidity and myotonia are distinct abnormalities of muscle tone that affect resistance and relaxation during movement. Although both involve altered muscle contraction, they arise from different neurological and muscular mechanisms.CharacteristicsRigidity is characterized by uniform resistance to passive movement across the entire range, independent of speed, affecting flexors and extensors equally. It may appear as lead-pipe rigidity (smooth, constant resistance) or cogwheel rigidity...

Summary

Progressive supranuclear palsy (PSP) pathology affects the spinal cord, particularly the cervical segment. Spinal interneurons in the anterior horn and intermediate gray matter show significant damage.

Area of Science:

  • Neuropathology
  • Neurodegenerative Diseases
  • Spinal Cord Anatomy

Background:

  • Progressive supranuclear palsy (PSP) is a neurodegenerative disease with complex pathology.
  • Spinal cord involvement in PSP has not been fully elucidated.

Purpose of the Study:

  • To characterize the histopathologic features of spinal cord lesions in PSP.
  • To review the literature on spinal cord pathology in PSP.

Main Methods:

  • Histologic examination of spinal cord lesions in 10 PSP cases.
  • Gallyas-Braak (GB) staining and AT-8 tau immunostaining.
  • Correlation with medulla oblongata pathology.

Main Results:

  • Atrophy and myelin pallor observed in anterior and anterolateral funiculi (8/10 cases).
  • Posterior funiculus remained preserved.
  • Neuropil threads and tau-positive inclusions found in gray matter, particularly affecting spinal interneurons in the cervical segment.

Conclusions:

  • The spinal cord, especially the cervical segment, is consistently affected in PSP.
  • Spinal interneurons and their processes in the medial anterior horn and intermediate gray matter are severely damaged in PSP.
